Eric noticed problems with vhost-scsi and virtio-ccw: vhost-scsi
complained about overwriting values in the config space, which
was triggered by a broken implementation of virtio-ccw's config
get/set routines. It was probably sheer luck that we did not hit
this before.

When writing a value to the config space, the WRITE_CONF ccw will
always write from the beginning of the config space up to and
including the value to be set. If the config space up to the value
has not yet been retrieved from the device, however, we'll end up
overwriting values. Keep track of the known config space and update
if needed to avoid this.

Moreover, READ_CONF will only read the number of bytes it has been
instructed to retrieve, so we must not copy more than that to the
buffer, or we might overwrite trailing values.

Commit 1cde2930 ("sched/preempt: Add static_key() to preempt_notifiers")
had two problems.  First, the preempt-notifier API needs to sleep with the
addition of the static_key, we do however need to hold off preemption
while modifying the preempt notifier list, otherwise a preemption could
observe an inconsistent list state.  KVM correctly registers and
unregisters preempt notifiers with preemption disabled, so the sleep
caused dmesg splats.

Second, KVM registers and unregisters preemption notifiers very often
(in vcpu_load/vcpu_put).  With a single uniprocessor guest the static key
would move between 0 and 1 continuously, hitting the slow path on every
userspace exit.

To fix this, wrap the static_key inc/dec in a new API, and call it from
KVM.

Pull ACPICA updates from Rafael Wysocki:
 "Additional ACPICA material for v4.2-rc1

  This will update the ACPICA code in the kernel to upstream revision
  20150619 (a bug-fix release mostly including stable-candidate fixes)
  and restore an earlier ACPICA commit that had to be reverted due to a
  regression introduced by it (the regression is addressed by
  blacklisting the only known system affected by it to date).

  The only new feature added by this update is the support for
  overriding objects in the ACPI namespace and a new ACPI table that can
  be used for that called the Override System Definition Table (OSDT).
  That should allow us to "patch" the ACPI namespace built from
  incomplete or incorrect ACPI System Definition tables (DSDT, SSDT)
  during system startup without the need to provide replacements for all
  of those tables in the future.

  Specifics:

   - Fix system resume problems related to 32-bit and 64-bit versions of
     the Firmware ACPI Control Structure (FACS) in the firmare (Lv
     Zheng)

   - Fix double initialization of the FACS (Lv Zheng)

   - Add _CLS object processing code to ACPICA (Suravee Suthikulpanit)

   - Add support for the (currently missing) new GIC version field in
     the Multiple APIC Description Table (MADT) (Hanjun Guo)

   - Add support for overriding objects in the ACPI namespace to ACPICA
     and OSDT support (Lv Zheng, Bob Moore, Zhang Rui)

   - Updates related to the TCPA and TPM2 ACPI tables (Bob Moore)

   - Restore the commit modifying _REV to always return "2" (as required
     by ACPI 6) and add a blacklisting mechanism for systems that may be
     affected by that change (Rafael J Wysocki)

   - Assorted fixes and cleanups (Bob Moore, Lv Zheng, Sascha Wildner)"

reverted by it is now addressed via a blacklist entry.
Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

The platform firmware on some systems expects Linux to return "5" as
the supported ACPI revision which makes it expose system configuration
information in a special way.

For example, based on what ACPI exports as the supported revision,
Dell XPS 13 (2015) configures its audio device to either work in HDA
mode or in I2S mode, where the former is supposed to be used on Linux
until the latter is fully supported (in the kernel as well as in user
space).

Since ACPI 6 mandates that _REV should return "2" if ACPI 2 or later
is supported by the OS, a subsequent change will make that happen, so
make it possible to override that on systems where "5" is expected to
be returned for Linux to work correctly one them (such as the Dell
machine mentioned above).

Pull module_platform_driver replacement from Paul Gortmaker:
 "Replace module_platform_driver with builtin_platform driver in non
  modules.

  We see an increasing number of non-modular drivers using
  modular_driver() type register functions.  There are several downsides
  to letting this continue unchecked:

   - The code can appear modular to a reader of the code, and they won't
     know if the code really is modular without checking the Makefile
     and Kconfig to see if compilation is governed by a bool or
     tristate.

   - Coders of drivers may be tempted to code up an __exit function that
     is never used, just in order to satisfy the required three args of
     the modular registration function.

   - Non-modular code ends up including the <module.h> which increases
     CPP overhead that they don't need.

   - It hinders us from performing better separation of the module init
     code and the generic init code.

  So here we introduce similar macros for builtin drivers.  Then we
  convert builtin drivers (controlled by a bool Kconfig) by making the
  following type of mapping:

    module_platform_driver()       --->  builtin_platform_driver()
    module_platform_driver_probe() --->  builtin_platform_driver_probe().

  The set of drivers that are converted here are just the ones that
  showed up as relying on an implicit include of <module.h> during a
  pending header cleanup.  So we convert them here vs adding an include
  of <module.h> to non-modular code to avoid compile fails.  Additonal
  conversions can be done asynchronously at any time.

  Once again, an unused module_exit function that is removed here
  appears in the diffstat as an outlier wrt all the other changes"

Merge tag 'module_init-alternate_initcall-v4.1-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux

Pull module_init replacement part two from Paul Gortmaker:
 "Replace module_init with appropriate alternate initcall in non
  modules.

  This series converts non-modular code that is using the module_init()
  call to hook itself into the system to instead use one of our
  alternate priority initcalls.

  Unlike the previous series that used device_initcall and hence was a
  runtime no-op, these commits change to one of the alternate initcalls,
  because (a) we have them and (b) it seems like the right thing to do.

  For example, it would seem logical to use arch_initcall for arch
  specific setup code and fs_initcall for filesystem setup code.

  This does mean however, that changes in the init ordering will be
  taking place, and so there is a small risk that some kind of implicit
  init ordering issue may lie uncovered.  But I think it is still better
  to give these ones sensible priorities than to just assign them all to
  device_initcall in order to exactly preserve the old ordering.

  Thad said, we have already made similar changes in core kernel code in
  commit c96d6660 ("kernel: audit/fix non-modular users of
  module_init in core code") without any regressions reported, so this
  type of change isn't without precedent.  It has also got the same
  local testing and linux-next coverage as all the other pull requests
  that I'm sending for this merge window have got.

Pull module_init replacement part one from Paul Gortmaker:
 "Replace module_init with equivalent device_initcall in non modules.

  This series of commits converts non-modular code that is using the
  module_init() call to hook itself into the system to instead use
  device_initcall().

  The conversion is a runtime no-op, since module_init actually becomes
  __initcall in the non-modular case, and that in turn gets mapped onto
  device_initcall.  A couple files show a larger negative diffstat,
  representing ones that had a module_exit function that we remove here
  vs previously relying on the linker to dispose of it.

  We make this conversion now, so that we can relocate module_init from
  init.h into module.h in the future.

  The files changed here are just limited to those that would otherwise
  have to add module.h to obviously non-modular code, in order to avoid
  a compile fail, as testing has shown"

Pull implicit module.h fixes from Paul Gortmaker:
 "Fix up implicit <module.h> users that will break later.

  The files changed here are simply modular source files that are
  implicitly relying on <module.h> being present.  We fix them up now,
  so that we can decouple some of the module related init code from the
  core init code in the future.

  The addition of the module.h include to several files here is also a
  no-op from a code generation point of view, else there would already
  be compile issues with these files today.

  There may be lots more implicit includes of <module.h> in tree, but
  these are the ones that extensive build test coverage has shown that
  must be fixed in order to avoid build breakage fallout for the pending
  module.h <---> init.h code relocation we desire to complete"

Pull __cpuinit removal from Paul Gortmaker:
 "Remove __cpuinit macros and users.

  We removed the __cpuinit stuff in 3.11-rc1 with commit 22f0a273
  ("init.h: remove __cpuinit sections from the kernel") but we left some
  no-op stubs as a courtesy to unmerged code.

  Here we get rid of the stubs as well, since (as can be seen in these
  changes) they are enabling use cases to sneak back in, primarily from
  older BSP code that has been living out of tree for some time prior to
  getting mainlined.  So we get rid of these "new" users 1st and then
  get rid of the stubs.

  Obviously, getting rid of the stubs can't happen until all the users
  are gone, so I had to keep this together as a series, even though some
  of these commits since got picked up into maintainers trees as well.

  The nature of this change is such that it should have zero impact on
  the generated runtime.

  This is one of several independent cleanup branches aimed at enabling
  better organization in the init.h and module.h code.  They have been
  getting coverage in the linux-next tree for the last month, in
  addition to my local testing, which also covers approximately a half
  dozen or more architectures"
